I put a fuse holder in the main feed to the electrical system. This one mounts on the starter. I also put a master cut-out switch in the starter to battery cable.
I use a 30 amp fuse. It's never blown, but I carry spares of course. I have a auto-reset 30 amp breaker that clips into the fuse holder and when I find it will give it a try....
Some day I'm going to change it to an in-line waterproof spade type fuse holder.
I think it's a good idea, as smoke is your only indication of a dead short in a non-fused system
